AMIT 135: Lesson 6 Grinding Circuit

The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.

Ball Mill

The ball mill is a tumbling mill that uses steel balls as the grinding media The length of the cylindrical shell is usually 1-15 times the shell diameter (Figure 811)The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20-40% water by weight.

The operating principle of the ball mill

The operating principle of the ball mill consists of following steps In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls.
